H represents horizont-al arms, upon which the feed-trough and the screenare supported, and which are secured with their outer ends to the underside of the bottom plate ot' the feed-trough. The inner ends of thesearms are secured in sockets, which are formed at the upper end of asleeve Zz., surrounding the shaft loosely. This sleeve rests upon acollar h', secured to the shaft.

h2 represents oblique brace-rods extending from the outer ends of thearms Il to ears h3, formed on the sleeve Zt.

t' represents tension-screws, which work in ears t', formed ou thesleeve ZL and bear downwardly against the arms 712 ofthe lowerscreenring g2 for the purpose of stretching the clothing of the screen.The hub of the lower ring g2 is mounted loosely upon the sleeve h, so asto be capable of vertical movement thereon. Upon stretching the wireclothing of the screen it assumes the curved form indicated in Fig. 5,its inclination becoming gradually steeper from the upper to the loweredge of the screen, so that the discharge of the coarse material isaccelerated while the material is held longest upon the upper peripheralportion of the screen upon which the separation takes place principally.

Zt represents an agitator, which is arranged in the annular feed-troughF for the purpose of distributing the material and breaking up any lumpsor aggregations which may exist therein. This agitator may be composedof an annular coil of wire, as represented in Fig. l, or of pins securedto the bottom of the feed-trough, as represented in Fig. G. Bothconstructions of the agitator are represented in Fig. 3.

L L represent traveling brushes, which sweep the under side of thescreen, the brush L bearing against the outer portion of the screen andthe brush L against the portion nearest the central opening. Thesebrushes are pivoted, respectively, to bars Z Z, which are in turnpivoted to arms Z2 Z3, projecting in opposite directions from a hub Z4,which is secured to the shaft B. The inner ends of the arms are providedwith Weights, by which the brushes are held against the under side ofthe screen.

M represents the lower hopper-shaped portion of the outer casing,provided at its upper end with a ange m, which is secured to thebase-flange Z4 of the upper cylindrical portion of the casing.

N represents an internal hopper arranged centrally in the outer hopper Mand underneath the central opening in the screen, so as t0 receive thecoarse material which tails ott from the screen. The internal hopper Nis provided with a central discharge-spout n and the outer hopper M witha swiveled dischargespout rn/,Which surrounds the inner dischargespoutn.

0 is a cross-piece, which is secured to the lower portion of the outerhopper M and provided with a step-bearing for the shaft B.

This cross-piece also supports the inner hopper N. e

P represents the horizontal driving-shaft. which is j ou rnaled inbearings secured to the base-flange d4 of the upper portion of the cas-.ing

p p are pulleys secured, respectively, to the driving-shaft P andworm-shaft CZ', and 132 represents a belt running around these pulleysand driving the worm-shaft.

The screen receives a horizontal oscillating motion from thedriving-shaft P by means of a iie'xible pitman Q, connecting a crank-pinr on the pulleyT p with a pin fr', secured to the top ring g of thescreen. sists of a forwardly-extending iiexible member q, attached tothe crank-pin and a rear- Wardly-extendin g flexible member q', attachedto the screen-pin, the two members being secured together with theirends, so as to form a pitman, which is doubled upon itself. Thisconstruction of the pitmanl permits the latter to move in the circularpath of the screen, which oscillates horizontally upon the shaft B as anaxis without binding and without producing a hard or violent shock orjar at' each reversal of the movement of the screen, but cushions themovement of the screen, so that the actual linear movement of the screenis somewhat longer than .the throw of the crank-pin by which it isproduced.

S represents a knocker, which strikes downwardly upon the upper ring gof the screen and which is attached to t-he outer end of a lever s,pivoted to the under side of the deck a. This lever is actuated by a cams upon the Worm-shaft CZ.

The material to be separated passes from the feed-disk upon the rotatingfeed-spouts, and is delivered by the latter to the feedtrough, overwhich it is distributed by the rotation of the feed-spouts. In thefeed-trough the material is further distributed by the oscillations ofthe trough which takes part in the oscillating movement of the screen.The movement of the material in the feed-spout toward the outer edge ofthe bottom is facilitated by the outward inclination of the uppersurface of the bottom. Before the material escapes from the spout itencounters the agitator, which oscillates with the spout and breaks upany lumps which the material may contain. The material drops from thefeedtrough upon the peripheral portion of the screen and passes inwardlyand. downwardly over the same, the iiner portions passing through thescreen into the outer hopper, while the coarser portions pass over thescreen and tail ott' through the central opening into the inner hopper.

When the machi ne is designed for scalping, the screen is clothed withwire-cloth, and when it is designed for separating middlings the screenis clothed with bolting-silk.

It is obvious that the annular feed-trough mayT be omitted and that therevolving feedspouts may deliver the material directly This pitman con-IIO l upon the screen; but this construction isless desirable, becausethe feed-trough serves to distribute the material and equalize the feedover the periphery ot the screen. A single rotating feed-spout may beused' instead of the double feed-spout which is shown in the drawings.

lVhen the material to be separated is of such a nature that either theoscillations of the screen or the knocker produces the necessaryagitation of the screen, the oscillatin g devices of the knocker may beomitted.

When several different kinds of material are to be separatedsimultaneously upon the same machine, Which is sometimes desirable insmall mills, the rotating teed-spouts are omitted and adistributing-cone T is substituted, which is secured to the screen andreceives the different kinds ot' material from different spouis t. Thereceiving-hoppers are divided by partitions t to receive and dischargethe several kinds of material separately. This construction of themachine is represented in Figs. S and 9.

I claim as my inventionl. The combination, with a circular screeninclined from the periphery to the center, of a feed-trough arrangedabove the peripheral port-ion of the screen and a distributerwhichconducts the material to be separated to the feed-trough, substantiallyas set forth.

2. The combination, with a circular screen inclined from the peripheryto the center, of a feed-trough arranged above the peripheral portion ofthe screen and a rotating feedspout which delivers the material to thefeedtrough, substantially as set forth.

The combination, with a circular screen inclined from the periphery tothe center, of a feed-trough arranged above the peripheral portion ofthe screen andan agitator arranged in said trough, substantially as setforth.

i. The combination, with a circular screen, of an annular feed-trougharranged over the peripheral portion of the screen and provided on theinner side of its out-er Wall with an annular dischargeopening,substantially as set forth.

5. The combination, With the circularscreen provided with an upperperipheral ring to which the soieeircloth is secured, of a centralshaft, a teedtrough having its bottom and inner Wall supported upon saidshaft and lts outer Wall and the peripheral screen-ring attached to thebottom of the trough, so as to leave an intervening discharge-opening,substantially as set forth.4 t

6. The combination, with an oscillating screen, of a iiexible pitmancomposed of two members arranged side by side and having their free endsconnected, respectively, with the screen and the crank-pin and theirfarther ends secured together, substantially as Set forth.

7. The combination, With a circular screen provided With a iixedperipheral ring and an axially-movable internal ring to which thescreen-cloth is secured, of a central shaft, a sleeve mounted onsaidshaft, arms secured to said sleeve and supporting the peripheral ring,and adjusting devices attached to said sleeve and engaging against theinternal ring, substantially as set forth.

Vitness my hand this 12th day of Marcin.
